IMPROVEMENT IN PUMPS.

Specification forming part of Letters Patent No. 185,8 [3, dated January2, 1877 application filed November 11, 1875.

To all whom it may concern:

Be it known that I, J OHN S. ADAMS, of Elgin, in the county of Kane andState of Illinois, have invented certain new and useful Improvements inForce-Pumps, of which improvements the following is a full, clear, andexact description, which will enable others skilled in the art to whichmy invention appertains to make and use the said improvements, referencebeing had to the accompanying drawings, forming a part thereof, and inwhich- Figures 1 and 2, Sheet 1, are side elevations, respectively, of aforce-pump provided with my improvements; Fig. 3, Sheet 2, a top or planview of the valve-box; Fig. 4, Sheet 2, an elevation of the piston; Fig.5, Sheet 2, a vertical central section through the piston-cylinders andvalvebox, and the parts therein; Fig. 6, Sheet 2, a vertical centralsection through the centering-blocks, and Fig. 7, Sheet 3, is a top orplan view, shown partly in section, of the walking-beam and some of theparts connected thereto.

Like letters of reference indicate like parts.

In the drawing, A represents the suctionpan or base of the pump, andconsists of a dish-shaped piece, from the central part of which projectsupwardly a tubular part, a, wherein are the ports a a. The bottom of thepart A is provided with an annular down weirdly-projecting flange, a. Bis the valvebox, and b, b, b, and b are valves arranged therein. 0 is afloor or horizontal partition dividing the box B into upper and lowerchambers, and c is the lower chamber thus made. The valves b and b playin seats arranged in the floor c. d is a horizontal partition, which,with the exceptions hereafter made, separates the box B from thepistoncylinders and air-chambers. The valves b and b play on seats inthe part (I. e is a Vertical wall or partition dividing into twochambers the space included between the partitions c and d, so that thevalves b and b communicate with one of these upper chambers, and thevalves b and b" with the other. f is a tube entering the chamber 0, andis attached to the part a by means of a screwthread. 0 is that part ofthe pump which constitutes the air-chambers 0 o, and also thepiston-cylinders o 0. The air-chambers communicate with each other, andlie in the same plane with the cylinders 0 0. The partition (1constitutes the bottom of the air-chambers, but the cylinders o 0communicate with the chamber below the said partition. D is a forkeddischarge pipe, the forked ends of which enter tubes, formingcontinuations thereof, and arranged in the air-chambers. Thesecontinuations extend nearly to the bottoms of the air-chambers, thusbeing directly over the valve b and b while the cylinders 0 0 aredirectly above the valves band b. E E are the pistons, and F F thepiston-stems. The pistons are flanged, as usual, as shown atpp, toreceive an expansible ring-packing, p. A groove is also sunken into thecentral part of the periphery of the piston, as represented by thebroken lines at 19 0", to receive small elliptic springs p 10', havingan outward pressure. q is a corrugated annular spring, made preferablyin sections, and arranged between the packingp and one of the shouldersor flangespp; and, in order that these corrugated springs may besecurely held in place, I set them into a groove, q. The piston-stemsare cogged, as shown at 1' 1, so as to operate as racks, in connectionwith the pinion hereinafter mentioned. G is a standard in the part G,and H is a spur-wheel or pinion having hearings in the part G, andarranged for engagement by the racks r r, the latter being held to thisengagement by means of the clasps or lugs r 1". I I are links pivoted tothe lower ends of the stems F F, and J J are tension-rods attached tothe upper ends of these links. Kis a floor intended to cover thereservoir, cistern, or tank containing the water into which the pump, inthe example shown, is intended to be submerged. The pipe D passes upwardthrough a central opening in this floor, and L is annular center-piecesurrounding this opening, and attached to the upper side of the floor.The upper and lower inner edges of the pins L are beveled, as shown inFig. 6, and M M are centering blocks or lugs, correspondingly beveled ontheir outer edges, and united by means of the screws s s, passing freelythrough one set of blocks-the upper set, for example-and into femalescrews in the other set, as shown. The single part of the pipe I) alsopasses between the inner ends of the blocks M M, which are there cut toreceive it. N N are uprights projecting from the part It. 0 is a rockingbeam. pivoted in the uprights N N, and having an elongated opening toreceive the discharge-pipe. The upper ends of the tensionrods J .I atescrew-threaded. and pass freely through the boxes 1 t. pivoted in forkedends of the beam 0. t t, Fig. 7, Sheet 3, are screw trunnions passingthrough screwthreaded perforations in the. forked ends of thewalking-beam, and entering socketsin the boxes 2 I, thus forming thepivots or trunnions on which the said boxes turn, and preventing thelatter from being detached from the beam unless the said trunnions orpivots are nnsciewed or temoved for that purpose. '0 r are nuts run uponthe upper ends of the rods J .l. and r v are sehscrews entering theboxes t t, and arranged for contact with the tension-rods. P is asocket, rigidly attached to the beam 0, and adapted to receive anoperating-levt-r, i which may be arranged either verti ally in thesocket, as shown in Fig. 1., or horizontally. as shown in Fig. 1. Theupper end of the tube 1) is preferably removable, and is bent downward,as shown.

B is a cock entering the lower part of one of the illlflilltllllbt'ls.and S is a rod rigidly attached to the spigot, and passing upwardthrough the floor K. \Vhen it is intended to use a horizontal arm orlever to work the pump, the bearings of the beam 0 may be sufiicientlyhigh to admit of the lever being moved with convenience. When the pumpis intended to be portable, and used, for example, as a garden-engine,the bearings of the beam may be much lower down than is shown, and thetloor K will not be essential. The base A, when constructed as shown anddescribed, steadies the lower part of the pump, and prevents the sandand soil from being sucked into the ports a a. By arranging theair-chambers and piston-cylinders in the saute plane, and constructingthe valve-box in the manner described, compactness, ease of action,facility of construction, and economy are secured. The corrugatedsprings, operating in connection with the ring-packing, tend to keep thelatter in contact with one of the shoulders of the piston, and theelliptic springs crowd out the ring-packing so as to recompense for wearand tear. The tensionrods, by being screw-threaded at the top andemployed in connection with the nuts and fastenings described, admit ofthe tightening of those parts which operate as pitmen; and lost motion,as well as the noise and wear and tear produced by loose joints, maythus be prevented. The beveled center-block, in connection with thecorrespondingly-beveled centering-pieces and the screws for tighteningthe latter, admit of the discharge-pipe being firmly held in place. Therod connected to the spigot, and extending above the floor, admits ofthe cock being controlled with convenience, and the water may be readilydrawn from the air-chambers. The pump may be operated by means of steam,suitable connections being made for that purpose.

1. The suction-pan A, provided with the flange a, in combination withthe inductiontube of a force-pump, substantially as and for the purposesspecified.
